 "summary": "NIST released a concept paper for Control Overlays for Securing AI Systems (COSAiS), which would tailor SP 800-53 security controls to AI use cases. The planned use cases include generative AI assistants, predictive AI, single-agent systems, multi-agent systems and controls for AI developers, informed by the AI 100-2 E2025 taxonomy. As of the project page, only an annotated outline for the predictive AI overlay (January 8, 2026) had followed; agent overlays had not been published.",
 "whyItMatters": "Agent-specific SP 800-53 overlays would give federal agencies and contractors auditable control baselines for agents; their absence is a notable gap.",
